X not numeric #13

Closed mattdpalm closed 2 years ago

mattdpalm commented 2 years ago

Hello,

I am getting the error

"Error in cor(thedata, use = "pairwise.complete.obs") : 'x' must be numeric"

Do all categorical variables need to be converted to numbers? Thank you,

SarBearSchwartz commented 2 years ago

Yes, but you probably should not do Pearson correlations with categorical variables with more than 2 levels.

Thanks, Sarah

Thanks for the question @mattdpalm - yes @SarBearSchwartz is correct, the current functions only accept numeric variables.

Hi—If I convert all categorical variables into a series of numeric indicators (0/1) would it work then? Thank you! On Sun, 19 Dec 2021 at 4:24 am, Martin Chan @.***> wrote:
